myQA® SRS

The power of SRS revealed!

The Digital SRS/SBRT Patient QA Solution

Fully utilize the capabilities of your stereotactic machine with the tool that enables more precise QA delivered in less time. The new myQA SRS solution uniquely combines the best of both worlds:

unrivaled accuracy and resolution of film QA,
with the proven efficiency of digital detector array workflow.

Treat more SRS/SBRT patients safely and with the confidence it’s done right.

105000 measurement pixels | 0.4 mm film-class resolution | Zero pixel spacing, no missing data | 12 x14 qcm sensor area

Experience with myQA SRS in the USA

“Patient-specific SRS and SBRT QA results look great using the myQA SRS even for very tight parameters of 2mm/2%. The digital detector QA workflow with myQA SRS is 10⁶ times faster and easier compared to using film. The film-equivalent resolution for our QA measurements is the basis for better and more meaningful SRS patient plan verification with a high sensitivity and specificity to detect real dosimetric issues.”

Experience with myQA SRS in the UK

“The high resolution of myQA SRS detector gives us high confidence in our stereotactic treatments, including SBRT spine, prostates and liver. We have achieved excellent Gamma Analysis QA results at 2 % and 2mm. The detector matched the performance of our ionisation chambers and compared excellently to film. The detector, phantom and software package is easy to use and integrates seamlessly into our myQA Platform. Obtaining instant high-resolution results without the need for lengthy film measurements is a big advantage.”

Automated beam-triggered measurement mode: save multiple mouse clicks and get QA results within seconds.

When Accuracy matters, Resolution matters!

myQA SRS provides the clinical resolution needed for the most advanced QA:

Measurement-based Patient QA is strongly encouraged e.g. by AAPM-RSS Medical Physics Practice Guideline 9.a. for SRS/SBRT.
However, publications have shown that “detector resolution is of main importance to avoid getting false positive [QA results].” A. Bruschi et al.: Detector resolution affects the clinical significance of SBRT QA. Find link to Publication here.
Other commercially available detector arrays for SRS/SBRT do not provide sufficient measurement resolution.
myQA SRS is the new and unique solution providing film-class resolution clinically needed to avoid false QA results.
Automated gantry angle correction with the wireless Gantry Sensor+.

Save hours of QA time vs. typical film dosimetry.
